SOLDERING-MAC-fINE. A`

ineaaoa Application filed December 26,1911. Serial No. 667,777.

To ill whom t may/concern:

Be it known thatl, CHARLES W. GRAHAM, a citizen of the United States, residing in New York, in the county of New York and State of New York,` have invented a new and useful Improvement in .Soldering-Machines, of which the following is a specification. f l

This invention relates to soldering machines. l n

rllhe object of the invention is to provide a machine which will solder covers to can bodies while the cans are in an inverted position, or that will solder the bottoms of can bodies while in an upright position, and is more particularly designed for use in connection with the soldering of iilled rectangular cans, which `have the covers mechanically attached to the lbody member before the solder is applied.

This invention is also particularly adapt-I ed to solder filled cansin which a part of the'can contents acts as a iiux for 'thesolder between the flanges ofthe cover and the body. The machine operates automatically to pick up cans in an inverted position at one point and automatically -dips the cans into a solder bath at another point, and ythe caps are then stripped from the carrier onto a receiving table or other suitabledevice, y L A. u

In order to-simplify the machine as much as possible, and to omit all unnecessary movable parts, especially as rconcerns the can body gripping members or chucks, although the latter may be employed without depai;'ting,from the spirit of the invention,

I` prefer to use magnetic devices for holding the lcans on position.v Y. I

More specifically, the invention consists in a rotatable carrier having a plurality of radially extending pivoted arms extending over a stationary table, a magnetized plate on the extremity of each of the pivoted arms, a solder bath `disposed below the the carrier in Aan, inverted path of travel of the magnetizedcan holding plates,l means for intermittently `:rotating the carrier and means for automatically lowering a pair of thevpivoted armswhile the carrier is at rest, whereby one of the chuck plates picks `up a can in an inverted positionand another armis simultaneously Specication of Letters Batent.-

partial, vertical section, upon `an enlarged scale, taken on the line 4 4- of Figfl and Fig. 5 is a diagrammatic view illustrating the circuits for magnetizing the 'can holding plates.

, In the drawing, 10 denotes any suitable having mounted therein a rotatableshaft 11, said shaft having keyed thereto aspider or carrier12, said spider being provided with -a plurality of radially extendingy members f13, each of said memy,bers having` pivotally mounted therein a radially extending arm l-l. Each of said arms is provided at its free end with a magnetized plate 15, which may be either lpermanently magnetized, or, as shown in the drawings, may be magnetized by means of electromagnets 16, energized from any suitable source of current 160.

` The spider 12 with its radially extending arms 14 rotates above a stationary table 17, said table `17 being provided at one point y :to center the can body to bel'soldered. AtA another point, the table is provided with a solder bath 19, said bath Y 19 comprising a member 20' provided with a channel portion 21 in which the molten solder is adapted to be retained, the channel 21 being of substantially the outline of the seam to be soldered, and said member 2O being out out portion in which is located a pipe 22 bymeansof which alv cooling blast of air may be projected againstthe surface of the can being soldered. Means for heating thesolder maybe `provided in theform of a gasburner 23 extending around and beneath the channel portion 2l. The carrier 12 is given an intermittent Vrotation by a Geneva gearv 24, driven from a shaft 25 which receives its power from any suitable source through the pulleys 26, shaft 27 and bevel gears 28. Located on the upper portion of the table l17 is a circular cam v track 29, on which are adapted to ride rollers 30, mounted'in' each ofthe arms 14. The

cam track 29 'is provided at points radially inline with the can centerin'gpins 18 and the solder bath with reciprocating slides 31 y of the same height as the track 29 mounted in guides 32, 'and adapted to be retracted .v

inwardly as by means of pins 33 and springs 34. Each of the slides 31 is provided with f a recessedA portion 35, which 4is normally projected outwardly beyond the cam track 29, but'which, when an, arm 14 ispositione'd inline with either the can centering pins 18 "or the bath, is adapted to be retracted, thereby allowing the roll 30 to fall: The downward movement of the roller 30 lowers the arm Q14, and at the same time, the plate 15. This movement at the can centering means will ypick yup one can and at the solder bath will dip the can, held to the platel, inthe solder bath 19. The slides 31 are controlled by means vof a cam 36, rotatablymounted 'on the shaft 11, saidk cam 36 beingprovided with a plurality of vnotches 37, which are engaged by a'roller' 38 on the inner end of ,l .each ofthe slides31. Thel cam 36 is continuously rotated'as by means of a gear 39 meshing with a gear 40,011 the rotatable Ishaft 25. After the cans have been'soldered, theyk are then removed from the plates 15 by means ofy a stripping plate 41,l which throws the cans out onto an adjacent table 42.

y The machine, as shown, is particularly adapted to operate on rectangular cans inwhich the cover flange is bent around or and the magnetized plate 15 will thenenv gage the invertedcan and lift the same, and

,e on the next movement of thecarrier will positionA the can over'l the solder bath k19. During the lnext period of rest, this arm'will 4'be lowered and' the seam immersed in the `bath 19, itbeing evident that the cam 36Yis so timed relative to the movements of the c'arrier,that a notch '37 in said cam 36'will be positioned opposite the roller 38 on each slide 31while the carrier is at rest. The machine is adaptedto operate on filled sardine j cans, in which the'oil serves as a'liuX for the solder, and during the movement from the centering pins 18to .the solder bath, this oil will have time to creep or seep down between-'the flanges on the cover and body.

I have shown one form of my invention,

but Il wish it'to beunderstood that the forni i shown is merely illustrative, and `that many changes vand, variations may be made in various details of ymy mechanism without departing from the spirit of the-invention, and all such changes and variations are contemplated as fairly come within the scope of the appended claims.

I claim c 1. Ina machine for soldering cans or other similar articles, the combination of a. solder bath, a magnetized plate adapted to attract and hold a can body, with a cover vsecured thereto, in an inverted position,
